--- Comment #5 from Yuri <yuri at tsoft dot com> ---
config.log doesn't contain the IEEE string even on amd64.

libgfortran/configure.host seems to only enable IEEE modules on i?86 | x86_=
64
architectures through this code:

> case "${host_cpu}" in
>   i?86 | x86_64)
>     if test "x${have_soft_float}" =3D "xyes"; then
>       fpu_host=3D'fpu-generic'
>     else
>       fpu_host=3D'fpu-387'
>     fi
>     ieee_support=3D'yes'
>     ;;
> esac

What does gcc need from OS for IEEE754?
Shouldn't it just compile with relevant to IEEE754 opcodes?=
